core: WeatherFlow Cloud is returning hail condition during snow/sleet/wintry mix

The problem

I have an automation that feeds WeatherFlow Cloud hourly forecast details to an LLM to get a summary of the next 24 hours of weather. I’m currently expecting (according to NWS forecasts) 12-24" of snow starting late tonight and into the next day, but my LLM summary keeps talking about hail.

Upon inspecting the returned results from weather.get_forecasts targeting my WeatherFlow Cloud entity, turns out that’s because the returned forecast lists hail as the condition quite a bit.

Here’s the next 8 hours as returned by weather.get_forecasts:

Here’s the same information captured from my station at tempestwx.com:

lightning and rainy seem to match up, but when the forecast condition starts saying hail, inspecting the element of the tempestwx.com forecast shows <span style="background-image: url(/images/Updated/sleet.svg"></span>, and sleet seems more accurate than hail.

Is it possible that some condition(s) are not being mapped correctly? My Tempest app and the web page summarize the days overall as “wintry mix”, and the Tempest API at https://weatherflow.github.io/Tempest/api/swagger/#!/forecast/getBetterForecast doesn’t seem to list hail as a potential condition string, so I’m not sure where that’s coming from.
